Scope

This standard specifies methods for the determination of the melting behavior of partially crystalline polymers by capillary and polarizing microscopy. Method A (capillary method) is applicable to all partially crystalline polymers and their compounds. Method B (polarized light microscopy) is suitable for polymers with birefringent crystalline phases. It is not suitable for compounds containing pigments and/or additives because it affects the birefringence of the crystalline regions of the polymer.
